Simulation Analysis of Electromagnetic Characteristics of Electric Vehicle Cable Under Tensile Condition

다국어 초록 (Multilingual Abstract)

This paper mainly studies the stress and strain characteristics of electric vehicle cables under tensile state and its influence law on the electromagnetic characteristics. Firstly, the structure and characteristics of new energy vehicle cables are analyzed, and the three-dimensional solid model of the cables is established. The finite element method is used to analyze the deformation law and stress change characteristics of cables under diff erent tensile load conditions, so as to achieve the resistance change law of cables. Then the equivalent modeling method is established to simulate the electromagnetic characteristics of the cable. It is found that the tensile deformation increases the electromagnetic field intensity of some parts of the cable, leading to the irregular distribution of electromagnetic field in the entire cable. Finally, the variation law of electromagnetic field during the cable deformation is summarized.
